Hi,

I am replacing an in-opening garage door with a rear face-mounted garage door.

Existing garage door:

The lintel above the garage door is not flush with the surrounding brickwork. I need to infill the gap to ensure I have a tight seal between the frame of the new garage door frame, and also be able to fix into it.

I have considered packing out with timber, but it is an awkward shape so will be difficult to achieve a tight seal.

Any advice or suggestions gratefully received.

Cheers

pack it out with ply, and silicon plastic board on top
